OPN Frequently Asked Questions

The order relevant ordering code is the SP number which is not descriptive though because it is simply a number that has no particular meaning. This means that you can´t see which product is behind the SP number (e.g. a discrete or microcontroller). It is also not possible to see differences between SP numbers. Our descriptive ordering code is the salesname. By knowing its nomenclature you can easily determine the product group and the product attributes. However, one Salesname (e.g. the microcontroller SAB C165-LM) can have several SP numbers. There are many reasons why this can happen: Different packing types, green and grey versions, customer specific versions etc. So using the SP number is not convenient because the product behind it is not visible, using the salesname is not sufficient because it can have many ordering codes. The OPN solves both problems by creating an ordering code on the SP level that shows all relevant attributes.

The OPN consists of an adapted salesname plus five additional digits describing the product in more detail.

Because special characters (e.g. commas, dots or dashes) can be disturbing, the OPN will not contain any special characters. That means that the adapted salesname is not equal to the regular salesname. For microcontroller products the adapted salesname will never show the "SA" prefix and the temperature identifier (third digit in the salesname) is moved to the end of the adapted salesname. In very few cases salesnames also had to be adapted slightly in addition to the deletion of special characters due to a maximum length of the OPN of 24 digits.

The OPN shows the RoHS status, the halogen status, the totally lead free status, the functional packing type and size as well as the moisture protection packing. Additionally you can see product variants in the last two digits: Every time a product doesn´t differ in its salesname or the attributes encoded in the OPN (RoHS, Halogen, Packing Type, Moisture Protection Packing and Packing Size), the designator increments.

The first OPN digit encodes RoHS, Halogen and totally lead free status, the second digit shows the combination of packing type and moisture protection packing and the third digit describes the packing size (e.g. 180mm reel or 330mm reel). Every attribute is shown by only one digit (e.g. 180mm = S).

The last two digits identify product variants.

There can be many reasons why a salesname has several ordering codes. To mention just a few examples: Customer specific versions, special test versions, ROM codes, different wafer thicknesses, different temperature ranges, different bonding wires etc. It is simply not possible to cover all of these reasons in a descriptive identifier.

Please refer to this answer if you want to know how to determine differences between designators.

Most of the differences can be found in the Product Change Notification (PCN). If you can´t find the difference between OPNs (their designators) contact your sales person, call us at 00800 951 951 951 or write an email to support@infineon.com.

The OPN is limited to 24 digits.

You can not only see the product and its attributes as you can in the salesname but also information about the RoHS status, the halogen status, the totally lead free status, the functional packing type and size as well as the moisture protection packing. You can also distinguish other product variants based on the designator.
The descriptive nature of the OPN and its order relevant level makes it easier to communicate: Talking about SP numbers is not convenient as they are simply numbers. Talking about Salesnames is not sufficient because one salesname can have several ordering codes.

Yes, every productive product (except for Engineering Samples) has an OPN.

No. The SP number is a vendors part number. Please talk to your sales contact if you plan to replace the SP# with the OPN.

In general - yes. The salesname can also only be used as a Customer Part Number because it is not unique. That means an order with the Salesname also needs to be translated into an SP number. Additionally it is possible that there are several SP numbers for one salesname which would increase the communication effort to find out the right SP number.

The OPN is shown on the Barcode Packing Label in the 2D barcode and it is shown in the type list of PCNs, PDs and Infonotes. If you use the OPN as your Customer Part Number (You order with a part number different from the SP number) then the OPN is shown on all documents that currently display the CPN: Invoice, Packing List, Order Confirmation, Debit&Credit Notes, Dispatch Note etc.

Not yet in a form readable for the human eye. It is shown in field 50P in the 2D barcode (data matrix code).

No. The datasheet is based on an aggregate level. It is possible that one datasheet is valid for several SP Numbers or several Salesnames. Additionally new OPNs (new SP numbers) are created too frequently to update datasheets.

The OPN is used as a customer part number (customer specific product name). For ordering purposes you tell us the OPN and we link it internally to the corresponding SP number. Now every time you order with the OPN we know the corresponding SP number.

If you would like to switch from your existing identifiers to the OPN, please contact your Infineon sales person.

None of the official product names Salesname, SP number or MA number are replaced. However, several years ago we introduced the proposed customer part number (pCPN) which will be replaced by the OPN.

You can keep ordering with the pCPN because we still maintain the link between your pCPN and the SP number. However, we will not provide you with the pCPN in pricelists or any other document or system anymore.

We strongly recommend to use the OPN for ordering or as your internal identifier instead of the pCPN. If you want to switch to the OPN, please contact your Infineon sales person.

Yes, except for Engineering Samples all Samples have an OPN.

Not necessarily. If a sample for product that comes on a 330mm reel is ordered it does not usually come on the reel itself.
Additionally it is possible that some sample attributes do not match the OPN attributes (e.g. OPN shows green but sample is grey).

No, Engineering Samples do not have an OPN.

Yes, Kits and Boards are marked with the OPN suffix "TOBO1…9" or “TOBP1…9”.
